>  Bochs supports the emulation of 4 different 3dfx Voodoo Graphics adapter models.
  The Voodoo1 and Voodoo2 models are 3D-only add-on cards and require a VGA
  compatible primary device. The Voodoo Banshee and it's successor Voodoo3 have
  both a VGA core and a 2D/3D core, so no other VGA card is required. The 2D/3D
  cards can be assigned to AGP if the i440BX chipset is selected (slot #5).
  </P
><P
>  To emulate the Voodoo1 or Voodoo2 device only the "model" parameter of the
  bochsrc option "voodoo" needs to be set. If the vga extension option is set
  to "voodoo" in that case, the primary display adapter is an ISA VGA card.
  </P
><P
>  For emulating the Voodoo Banshee or Voodoo3 adapter, the vga extension option
  must be set to "voodoo". Using a different primary display adapter and a
  Banshee compatible device with it's VGA interface disabled is not
  implemented yet. Both Banshee and Voodoo3 currently need a specific external
  VGA BIOS, since a Voodoo extension for the LGPL'd VGABIOS is not written yet.
  </P

>  These bochsrc settings should be used for Voodoo Banshee PCI:
